Water line repair in Chicago, IL
The water service line runs from the curb stop near the street to your house, buried below the frost line. A leak shows up as a soggy patch in the yard, low pressure throughout the house, or a meter that never stops. Repair means finding the leak, then fixing that spot or replacing the line.

Water line repair in Chicago: what's different
Many older Chicago homes are served by lead service lines, and the city has a replacement program. Leaks in the service line show up as low pressure, a wet spot near the curb or a higher bill.
A plumber locates the leak and repairs or replaces the line. Permits come from the Chicago Department of Buildings, and the Department of Water Management handles the main.
Chicago's deep frost line means service lines are buried deep, which affects how repairs are made and what they cost.

How to find and test your main water shutoff
